=Beam Line info=

Machine: 25b Linac

0<math>&deg;</math> port

Beam Energy: 8 MeV

Rep Rate: Max (150Hz?)

Pulse Width: 100ns

=Run Plan=

==To find operating point==

- Will use 15 OSLs from reproducibility study to make sure that dose is within acceptable range

==Experiment==

85 Nanodot OSLs for use (dose not include OSLs from reproducibility study)

- upper limit of OSLs is 15Gy, want to be around 7.5Gy with multiple pulses

Will talk to engineers about double pulsing and guaranteeing number of pulses and update.
